For example, the relative terms at least include the degree of error associated with the measurement of a particular value, the tolerance caused by manufacturing, assembly, use, and the like associated with a particular value. Such terms should also be considered to disclose a range defined by the absolute values of the two endpoints.

[0055] Please refer to Figures 1 to 5 The embodiment provides a multi-station platform, which comprises a base 1, a jig 2, a transfer mechanism 3 and an adjusting mechanism 4. The jig 2 is configured to carry and fix a product 100. The transfer mechanism 3 is arranged on the base 1, and is configured to drive the jig 2 to move to a product detection station. The adjusting mechanism 4 is arranged between the transfer mechanism 3 and the jig 2, and is used to adjust the height position of the jig 2. The jig 2 is provided with at least two, and the number of the transfer mechanism 3 and the adjusting mechanism 4 corresponds to the number of the jig 2. The plurality of transfer mechanisms 3 can transport a plurality of products 100 to the same product detection station. In the embodiment, the jig 2 is provided with two, and the number of the transfer mechanism 3 and the adjusting mechanism 4 is correspondingly set to two.

[0056] During detection, the product 100 to be detected is first placed on the jig 2, which carries and fixes the product 100. Then, the transfer mechanism 3 moves the jig 2 carrying the product 100 to the product detection station according to a preset trajectory. At this time, the optical detection element starts to comprehensively detect the product 100 and obtains corresponding data. After detection is completed, the jig 2 returns to the initial position under the drive of the transfer mechanism 3, facilitating subsequent operation by the operator. At the same time, the next jig 2 repeats the above process, and the process is repeated one by one to realize continuous detection of the product 100.

[0057] It should be noted that the adjustment of the height of the jig 2 is performed before detection to ensure that the product 100 is in the best position for detection. It can be understood that multiple jigs 2 are provided, and the remaining jigs 2 can be loaded and unloaded while the previous jig 2 is in the product detection station. Compared with a single jig 2 carrier, the overall production cycle can be effectively shortened, and the production efficiency can be improved.

[0058] It can also be understood that the number of transfer mechanisms 3 and adjustment mechanisms 4 corresponds to the number of jigs 2, so that each jig 2 can be independently and quickly driven to the product detection station, thereby enabling multiple jigs 2 to share a set of optical detection elements, thereby reducing production costs. In addition, using only one set of optical detection elements to detect the products 100 on multiple jigs 2 can avoid inconsistencies in detection results caused by performance differences and calibration errors between multiple sets of optical detection elements, ensuring that all products 100 are detected under the same detection conditions and standards, improving the comparability and reliability of the detection results, and facilitating unified evaluation and control of the quality of the products 100. It is especially suitable for products 100 such as mobile phone key glasses, which have small volume and require high consistency in color difference and height.

[0059] Specifically, the adjustment mechanism 4 includes a mounting member 41, a carrying member 42, and a connecting assembly (not shown in the figure). The transfer mechanism 3 is in transmission connection with the mounting member 41 to drive the mounting member 41 to move. The carrying member 42 is movably arranged on the mounting member 41, and the carrying member 42 is used to carry the jig 2. The connecting assembly is used to mount the carrying member 42 on the carrying member 42 and adjust the height of the carrying member 42 on the mounting member 41.

[0060] In actual detection, different products 100 may have different detection requirements, and the products 100 need to be adjusted to a specific height to adapt to the optical detection element. Therefore, the precise height adjustment function provided by the adjustment mechanism 4 can ensure that the product 100 is in the best detection position, improving the accuracy and reliability of the detection. By adjusting the height of the carrying member 42 on the mounting member 41 through the connecting assembly, the height position of the jig 2 can be accurately controlled.

[0061] In particular, the connecting assembly includes an adjusting member and a connecting member. The adjusting member is screwed on the mounting member 41 and can jack up the carrier 42. The connecting member is screwed through the carrier 42 and the mounting member 41 to lock the carrier 42 on the mounting member 41.

[0062] During adjustment, the adjusting member is first rotated to change its relative position with the mounting member 41 by screw transmission, so as to jack up or lower the carrier 42, and the jig 2 is synchronously lifted or lowered. Then, the adjusting member is fine-tuned according to actual requirements by means of a measuring tool or a preset standard, until the jig 2 reaches the required height. After the jig 2 reaches the required height, the connecting member is screwed through the carrier 42 and the mounting member 41, and after being tightened, the carrier 42 is fixed on the mounting member 41, so as to ensure that the height of the jig 2 remains unchanged during subsequent transfer and detection, and to ensure stable and accurate detection.

[0063] It can be understood that the simple adjusting member and the connecting member are easy to disassemble and install, and can reduce the use cost.

[0064] Further, a plurality of adjusting members and connecting members are provided. The plurality of adjusting members can make the carrier 42 uniformly stressed during height adjustment, so as to avoid the inclination or uneven stress of the carrier 42 caused by single-point adjustment, thereby making the height adjustment of the jig 2 more accurate and flat, ensuring that the product 100 on the jig 2 is in a horizontal or specific standard position, and improving the accuracy of detection or processing. In addition, the plurality of adjusting members can share the load together, thereby increasing the stability and reliability of the entire system.

[0065] More importantly, the plurality of adjusting members can realize independent adjustment at different positions, so that the carrier 42 can be fine-tuned in multiple dimensions. For example, when facing the jig 2 with irregular shape or needing different height adjustments in different areas, the adjusting members at different positions can be controlled respectively to meet the complex adjustment requirements, thereby increasing the adaptability and flexibility of the adjusting mechanism 4.

[0066] To further improve the accuracy of the detection result, the base member 1 is a marble platform. It can be understood that the marble has high hardness and good rigidity, and can withstand the weight and impact force of the jig 2 during the transfer process, and is not easy to deform, so that the jig 2 can remain stable during the transfer process, and the positional deviation caused by the deformation of the base member 1 is reduced, thereby improving the transfer accuracy. In addition, the surface of the marble platform is finely processed and has high flatness and smoothness, which helps the transfer mechanism 3 to accurately move according to the preset path and speed during the transfer of the jig 2, thereby realizing more accurate positioning.

[0067] Generally, the flatness accuracy of the marble platform can reach the micron level, which can provide a high-precision reference surface for detection. Specifically, the marble platform can achieve a flatness accuracy of 0.005 mm. It should be noted that the specific structure of the marble platform is designed according to the actual use scene, and this embodiment does not make specific requirements and limitations.

[0068] In the present embodiment, the transfer mechanism 3 includes a first movement module 31, a second movement module 32, and an adapter 33. The first movement module 31 is arranged on the base 1, and the first movement module 31 includes a first movement part capable of moving in a first horizontal direction. The second movement module 32 is arranged on the first movement part, and the second movement module 32 includes a second movement part capable of moving in a second horizontal direction, and the first horizontal direction is perpendicular to the second horizontal direction. The adapter 33 is arranged on the second movement part, and the adjustment mechanism 4 is arranged on the adapter 33.

[0069] It can be understood that by moving the first movement module 31 in the first horizontal direction and the second movement module 32 in the second horizontal direction perpendicular to the first horizontal direction, the adapter 33 can move freely in a two-dimensional plane, that is, the jig 2 can move freely in a two-dimensional plane, thereby meeting the adjustment or detection requirements of the jig 2 at different positions.

[0070] Preferably, the first movement module 31 and the second movement module 32 are both linear modules. It can be understood that the linear module adopts a precise guide rail and transmission system, such as a ball screw or a synchronous belt transmission, which can achieve high-precision positioning and maintain accurate position control within a long stroke, thereby ensuring that the jig 2 is accurately transported to the product detection station to improve the accuracy of the detection result. In addition, the linear module has high driving efficiency, shortens the transfer time, and improves the production efficiency. It should be noted that the specific model of the linear module can be selected according to the actual application scene, and this embodiment does not make specific requirements and limitations.

[0071] Specifically, the jig 2 includes a bottom plate 21, a fixing member 22, a positioning member 23, and a driving assembly 24. The bottom plate 21 is detachably connected with the carrier 42. The fixing member 22 is arranged on the bottom plate 21, and the fixing member 22 is used to carry and fix the product 100. The positioning member 23 is movably arranged on the fixing member 22, and the positioning member 23 is configured to cooperate with the fixing member 22 to position the product 100. The driving assembly 24 is arranged on the bottom plate 21, and the driving assembly 24 is configured to drive the positioning member 23 to move. It should be noted that in the present embodiment, the bottom plate 21 and the carrier 42 are detachably connected by a bolt structure, and in other embodiments, structures such as clamping, magnetic attraction, etc. can also be used.

[0072] When the product 100 is clamped, the product 100 is first placed on the fixing member 22, the structure on the fixing member 22 matched with the bottom of the product 100 provides stable support for the product 100, then the driving assembly 24 drives the positioning member 23 to move, the positioning member 23 cooperates with the fixing member 22 to accurately position the product 100, after positioning, the fixing member 22 applies fastening force to the product 100 by mechanical clamping, magnetic adsorption or vacuum adsorption, etc., to firmly fix it. At this time, the product 100 is stably clamped on the jig 2, which can meet the subsequent detection requirements and ensure that the position of the product 100 does not change during detection.

[0073] Preferably, the fixing member 22 includes a placing groove 221 for accommodating the product 100, one side of the placing groove 221 is provided as open to form an opening, and the positioning member 23 includes a closing part 231 capable of closing the opening. When the product 100 is placed in the placing groove 221, the closing part 231 can accurately limit the product 100, and the driving assembly 24 drives the positioning member 23 to move to close the opening by the closing part 231, so as to realize accurate positioning of the product 100 by the closing part 231 and the other parts of the placing groove 221, ensure that the product 100 is always in the placing groove 221 during detection, reduce position deviation, and improve processing precision and detection accuracy. In addition, the above structure is relatively simple and easy to design, which reduces the design and manufacturing difficulty of the jig 2 while ensuring the positioning and fixing functions of the product 100, and is convenient for later maintenance and maintenance, and easier to repair and replace parts when a fault occurs.

[0074] It should be noted that in the present embodiment, the fixing member 22 fixes the product 100 by vacuum adsorption, specifically, at least one vacuum adsorption hole is provided on the bottom wall of the placing groove 221, and a vacuum generator provides vacuum adsorption force for the product 100 positioned in the placing groove 221 through the vacuum adsorption hole to fix the product 100. The structure of the vacuum generator and its working principle are both prior art, so they will not be described here. It should also be noted that the driving assembly 24 includes a cylinder and a telescopic spring respectively located on both sides of the positioning member 23, so as to drive the positioning member 23 to move by the cylinder and drive the positioning member 23 to reset by the telescopic spring.

[0075] It should also be noted that the specific structure of the placing groove 221 of the fixing member 22 is set according to the size and shape of the product 100, so it will not be described here. In addition, the number and arrangement of the placing groove 221 can also be set according to the size and shape of the product 100, for example, the placing groove 221 can be arranged in multiple rows to improve detection efficiency, because the volume of the mobile phone key glass is small. In the present embodiment, the placing groove 221 is arranged in two rows, and each row has eight.

[0076] The embodiment further provides an optical detection device, which comprises a rack, an optical detection element and the multi-station platform, the optical detection element and the multi-station platform are arranged on the rack, and the multi-station platform is located below the optical detection element. The multi-station platform is located below the optical detection element, which is beneficial to optimize the optical path of optical detection.
